7 Claims.

My invention relates to improvements in bottle bottom inserting and spinning mechanism for paper bottle making machines, and the object of the invention is to devise a simple mechanism 5 for automatically successively feeding discs to parts in the position'they assume when the botthe point of insertion and inserting them in the bottle bottom and then transferring the bottle body and the inserted disc to a spinning point, and then spinning the edge of the bottle body and disc; and it consists'essentially of the arrangement and construction of parts as hereinafter more particularly explained.

Fig. 1 is a side elevation showing a portion of the body of a paper bottle making machine and the bottom inserting and spinning mechanism carried thereby.

Fig. 2 is an enlarged detail elevation of the bottle bottom inserting mechanism showing the parts-in the position they assume as the disc blanks forming the bottle bottom are fed into the mechanism.. y

Fig. 3 is a similar view to Fig. 2 showing the tle bottom is being inserted in the bottle body.

Fig. 4 is a plan view of the parts shown in Figs. 2 and 3.

Fig. 5 is a, side elevation of the mechanism shown in Figs. 2 and 3 looking in a direction at right angles thereto.

Figs. 6, '7 and 8 are fragmentary sectional details showing respectively. the position assumed during the feeding of the blank into the receiving recess of the operating arm, the position assumed prior to the insertion of the blank in the bottle body-and the position assumed after the insertion of the blank in the bottle body.

Fig. 9 is a detailed View of the operating cam for operating the inserting mechanism.

Fig. 10 is an enlarged sectional detail through the spinning mechanism.

Fig. 11 is an enlarged elevation of the spinning mechanism.

Fig. 12 is an enlarged perspective detail of the spinning head, and

Fig. 13 is a. further enlarged fragmentary section through a. portion of the spinning head showing the bearing pins engaged by the portions of the bottle bottom to be' spun.

In the drawings like letters of reference indicate corresponding parts in each figure.

I indicates the body of the machine upon which is secured a bracket 2 carrying a standard 3 provided with a vertical slot 4, from which extends studs 5 and 6 adjacent its upper and lower ends, carrying friction rollers 'l and 48. 9 isy a bar which fits between the upper and lower pairs of friction rollers 'I and 8 to move vertically therebetween.

l is a projecting 'arm extending rigidly from the bar 9 through the -slot 4 of the standard 3. II is a rocking shaft mounted in bearings I2 and I3 carried by the body of the machine, the shaft I I at one end being provided with a short arm I4 connected by a link I to the projecting arm I0 vcarried by the vertically movable bar member 9. I6 is a cam shaft to which is secured a cam member I'I having a cam groove I8 with which coacts the cam roller I9 carried by the vertical movable member 9.

20 is a flange plate carried by the bracket 2 extending in a vertical position and in which is located the orifices 2| and 22. 23 is a trough like receptacle secured at one end in the orice 2l, the inner end of the trough being provided with a circular portion 24 fitting the orice 2l and extending flush with the outer face of the flange plate 20. 25 is a stationary` rod extending from the flange plate 20 and on which is slidably mounted the hub 26` of a pressure plate .21 so as to slide longitudinally thereof. 28 is a pile of discs which are to be fed forward by the pressure of the plate 21 bearing against the rear end of the pile, such pressure being exerted by a weight 29 hung upon a cable 3U extending over guide pulleys 3l and 32.

33 is a long arm secured at the opposite end of the rocking shaft I I, the inner face of which slidably engages the outer face of the ange plate 20 and has formed therein a circular recess 34 corresponding in depth to the depth of each disc of the pile 28 and from which extends an orifice 35 through which the inserting plunger hereinafterdescribed operates.

By the operation of the cam I1 imparting ver- 'tical movement to the bar 9, the shaft I I is rocked so as to swing the arm 33 so that the recess 34 is alternately in a position concentric with the orifice 2l and the orifice 22 of the flange plate 20. Whenthe recess 34 is opposite the orifice 2|, the operation of the pressure plate 2l forces one of the discs of` the pile 28 into the recess 34. The

a mandrel 31. 39 is a bearing member in which is held a pusher rod 40 which moves longitudinally therein and is provided, at its outer end, with a pusher head 4I which engages the disc 28 and forces it through the orifice so as to upset the annular edge of the disc as indicated at 28x forcing the disc into the body of the bottle so that the upset edges 28x thereof engage the inner annular face of a bottle body.

42 is a cam secured to the shaft I6 and provided with a cam groove 43 into which the cam roller 44 extends, the cam roller 44 being carried by the pusher rod 40. It will, therefore, be seen that the cam 42 is so timed thatwhen the disc 28 is brought opposite to the orifice 22 the pusher rod and head 4I are forced forward to insert the disc in the bottle body as above described.

^ After the disc has been inserted in the bottle,

the turret 36 is again rotated another step so that the bottle body with its inserted disc is carried opposite to the spinning point and spun by mechanism which I will now describe.

45 is the main operating shaft of the spinning mechanism from which the shaft I6 is driven through suitable gearing indicated at 45x. 46 is a base member supported upon the main body of the machine and carrying the stationary bearing member 41 carrying the spaced apart bearings 41x and 41 in which is mounted the independently driven shaft 53. The upper portion of the bearing member 41 is formed into a longitudinal guideway 48 in which is slidably mounted an upper bearing member 49 carrying the spaced apart bearings 49x and 49. 50 is a short shaft `iournalled in the bearings 49x and 49 and bearing at its inner end against a thrust bearing 5I. end of the bearing member 49.

54 are lugs extending from the stationary bearing member 41 in which is mounted a short shaft 55. 56 is an arm secured at one end on the shaft 55 and pivotally connected at its opposite end between the lugs 52 as indicated at 51. 58 is an arm also mountedupon the shaft 55 and pro- V vided at its free end with a cam roller 59 coac ing with the cam 60 secured to the shaft 45. The arms 56 and 58 are adjustably connected together by means of the spaced apart lug members 6I and 62forming part of the arm 58 and interposed lug member 63 forming part of the arm 56.

64 and 65 are set screws extending through the lugs 6| and 62 so as to bearfagainst opposite sides I of the lug 63. By this means the arms 56 and 58 After the turret has been turned so as to carry the mandrel 31 from'a position opposite the orice 22 to a position opposite the spinning head 69, the cam 69 coacting with the arms 58 and 56 force the upper bearing member 49 together with the spinning head 69 against the rim of the bottle body and-the opposite portion of the disc1 end so as to spin it inwardly, the head 69.revolving at a high rate of speed with the bottle rim in engagement with the roller pin 1I thereby reducing the friction to a 52 are lugs extending from the innerY From this description it will be seen that I have devised a very simple device by which the -discs forming the bottle ends of a paper bottle are inserted in the body of the bottle and the rim of the bottle spun around'so as to retain the inserted discs in position within the bottle body.
